Location Based Automatic Extraction power line image UAV

An automatic extraction location based UAV power line image, including the use of flight strips bis UAV flight, aerial images acquired; Aerial power line automatic extraction of aerial image was extracted with LSD line detection method; using the power line radiation characteristics of the crude extract, the connectivity negative context; seek and removing context LSD detected image, to exclude the remaining background information, while the detected power line connected; Aerial power line three-dimensional data is positioned, nuclear line image capture, and epipolar lines intersect the wires of the same name request point coordinates, a forward intersection, to obtain three-dimensional data of the power line. The present invention improves the efficiency of the three-dimensional transmission line system, three-dimensional coordinates to obtain more accurate, cost reduction of a power line transmission line corridor.
